Growth and fabrication of semiconductor nanomembrane structures for basic research and potential device applications


Nanomembranes, developed in the last decade, constitute a novel class of two-dimensional materials. They have attracted applied and basic research due to their potential use in hybrid material based device architectures, flexible electronics or for studying basic effects on the nanometer scale. In this project, we aim to build the bridge between fundamental and applied research. We intend to study the fundamental properties of nanomembrane systems in regrade for their potential applications in optics or electronic devices. We plan to carry out fundamental growth studies using molecular beam epitaxy to understand the formation of nanostructures on top of semiconductor membranes. In a second step, we will investigate the suitability of these membranes for the growth of optical device. Beside the investigation of membranes as virtual, compliant substrates, we would like to develop a new class of plasmonic devices based on rolled-up semiconductor membranes. For this propose, we will optimize and study the integration of a new class of strain free, mesoscopic GaAs emitters into rolled-up tube resonators. As plasmonic gain material, we like to use graphene due to its good plasmonic response in the visible range as well as better transparency compared to Ag or Au. Before the experimental realization of such structures, we plan to carry out finite difference time domain (FDTD) calculation to optimize our design.If granted, the project will not only support the molecular beam epitaxy facilities of the LNNano, but also will allow this facility to continue to offer high quality III-V heterostructures to the Brazilian research community.
